Definitions
- the invention relates to a method for moisture-tight covering of a connection point between an electrical conductor surrounded by an insulation and a contact element according to the preamble of the claim.
- Such a method is for example from the JP 2010 192129 A out.
- the method is used wherever an electrical contact point is to be protected from moisture.
- the individual wires made of flexible conductors are referred to in the following as "stranded".
- As the electrically conductive material of such strands in particular copper and aluminum and alloys of these materials are used.
- a field of application for the strands is, for example, the engine compartment of motor vehicles.
- moisture and other environmental influences and vibrations must be considered.
- a protective body made of insulating material is injected around a connection point in an injection molding tool.
- a hose made of shrinkable material which is coated on the inside with sealing material, is pushed over a connection point which, after being heated, lies tight against its base.
- Both methods are not only expensive, but they can not ensure the required seal also, because neither the spray material of the protective body nor the sealing material of the hose penetrates sufficiently deep between the individual wires of the strand. Also a between the conductor and its insulation existing gap is not sealed in both methods, so that in the joint penetrated moisture can also penetrate in the longitudinal direction of the conductor. It may then cause a short circuit at the far end of the conductor and cause corrosion in the joint, which can quickly destroy it.
- JP 2010 192129 A describes a method by which a two staple having contact element at the end of a stripped, designed as a stranded electrical conductor is attached.
- one of the staples is wrapped around the insulation of the conductor and the other around the conductor.
- a sealing material is applied to the conductor from above. It penetrates the ladder and hardens.
- the invention has for its object to make the method described above so that an effective seal the connection point between the strand and contact element is achieved against moisture.
- an initially flowable sealing material is applied in sufficient quantity to the connection point between the strand and the contact element, in particular the strand, which penetrates into the strand due to its viscosity.
- the sealing material is applied in such an amount that it extends beyond the insulation of the strand, so that the gap between the strand and insulation is closed by the sealing material. In this case, the sealing material penetrates, at least over a short distance, into the gap between the strand and the insulation surrounding it.
- the sealing material also extends beyond the contact element, so that the connection point is completely covered moisture-tight from above. This is made possible or completed by the foil arranged below the connection point and resting against the insulation of the strand and the contact element, which serves as a boundary for the sealing material.
- the sealing material then also attaches to the contact element from below.
- the film is firmly bonded to the sealing material, so that there is a closed around the junction and after curing of the sealing material stable sealing body. Overall, it effectively seals the joint against moisture.
- Fig. 1 is an electrical line L shown, which consists of a strand 1 and a same surrounding insulation 2.
- the strand 1 is according to Fig. 2 constructed of a plurality of individual wires 3, which are preferably twisted together or twisted.
- the individual wires 3 may consist, for example, of copper or of aluminum or of a copper alloy or an aluminum alloy.
- the insulation 2 may for example consist of polyethylene or polyurethane. It is according to Fig. 1 removed at the end of the line L, so that the strand 1 is exposed there and can be used for direct connection to electrical contacts or electrical contacts.
- the stranded wire 1 is electrically connected to a contact element 4 made of metal, which belongs to any electrical device 5, which is indicated only schematically.
- the contact element 4 may be, for example, a flat strip with a rectangular cross-section. It can also have a different geometric shape.
- the strand 5 is summarized at its free end with advantage and compressed with advantage that no individual wires 3 protrude sideways.
- the strand 1 with the contact element 4 is electrically conductive connected, for example, soldered, but advantageously welded.
- the compacting and soldering or welding of the stranded wire 1 to the contact element 4 can also be carried out in only one operation. A resulting by this treatment, dashed edge ram V goes out schematically Fig. 3 out.
- Such a joint V is covered by the method according to the invention, for example, moisture-tight as follows: First, a film 6 of insulating material is applied from below to the connection point V or the connection point V is placed on the film 6. Then according to Fig. 4 between the film 6 and the contact element 4, a spacer 8 is attached, which has a relation to the surface of the contact element 4 smaller area. In both cases, the film 6 rests both on the insulation 2 of the line L and on the contact element 4 or on the spacer 8. It protrudes with advantage on all sides beyond the actual connection point V between the strand 1 and contact element 4 addition.
- materials for the film 6 for example, polyethylene terephthalate, polyurethane, polyvinyl chloride, polyamide and polyethylene are suitable.
- a first flowable sealing material is applied from above to the joint V, preferably directly to the strand 1. This can be done for example by pouring or dripping or using a kind of syringe.
- Suitable as a sealing material are, for example, polyvinyl chloride, polyurethane, polyamide, silicone rubber and fluorinated ethylene propylene and Perfluoralkoxypolymer. It can consist of only one material, but also be designed as consisting of two different components existing material.
- the flowable sealing material penetrates between the individual wires 3 of the strand 1. It is trapped in its downward movement by the film 6, so that it can spread only in the joint V itself and around them.
- the sealing material penetrates at least over a short distance in the between Litz 1 and insulation 2 of the line L existing circumferential gap, which is thereby closed. Due to the spacer 8, the sealing material can also spread between contact element 4 and foil 6. It extends finally on the one side to the insulation 2 of the line L and on the other side to over the contact element 4.
- the sealing material hardens after its application relatively quickly, so that a mechanically stable sealing body 7 results, the joint V effectively seals against moisture.
- the existing of any material spacer 8 may for example be designed as a disc or consist of ribs, which can be arranged or mounted on the same before mounting the film 6 to the insulation 2 of the conductor 1 and the contact element 4 on the same.

Description
Die Erfindung bezieht sich auf ein Verfahren zum feuchtigkeitsdichten Abdecken einer Verbindungsstelle zwischen einem von einer Isolierung umgebenen elektrischen Leiter und einem Kontaktelement gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a method for moisture-tight covering of a connection point between an electrical conductor surrounded by an insulation and a contact element according to the preamble of the claim.
Ein derartiges Verfahren geht beispielsweise aus der
Das Verfahren wird überall dort eingesetzt, wo eine elektrische Kontaktstelle vor Feuchtigkeit geschützt werden soll. Die aus Einzeldrähten bestehenden, flexiblen Leiter werden im folgenden als "Litze" bezeichnet. Als elektrisch leitendes Material solcher Litzen werden insbesondere Kupfer und Aluminium sowie Legierungen dieser Materialien verwendet. Ein Einsatzgebiet für die Litzen ist beispielsweise der Motorraum von Kraftfahrzeugen. Hier müssen bezüglich der Abdichtung der Verbindungsstellen zwischen Litzen und Kontaktelementen zusätzlich Feuchtigkeit und andere Umwelteinflüsse sowie Erschütterungen berücksichtigt werden. Bei bekannten Verfahren wird beispielsweise um eine Verbindungsstelle in einem Spritzgießwerkzeug ein aus Isoliermaterial bestehender Schutzkörper herumgespritzt. Bei einem anderen bekannten Verfahren wird ein aus schrumpfbarem Material bestehender Schlauch, der innen mit Dichtmaterial beschichtet ist, über eine Verbindungsstelle geschoben, welcher sich nach Erwärmung dicht an seine Unterlage anlegt. Beide Verfahren sind nicht nur aufwendig, sondern sie können die erforderliche Abdichtung auch nicht gewährleisten, weil weder das Spritzmaterial des Schutzkörpers noch das Dichtmaterial des Schlauches ausreichend tief zwischen die Einzeldrähte der Litze eindringt. Auch ein zwischen dem Leiter und seiner Isolierung vorhandener Spalt wird bei beiden Verfahren nicht abgedichtet, so daß in die Verbindungsstelle eingedrungene Feuchtigkeit auch in Längsrichtung des Leiters vordringen kann. Sie kann dann am fernen Ende des Leiters einen Kurzschluß verursachen und in der Verbindungsstelle zu Korrosion führen, durch welche dieselbe schnell zerstört werden kann.The method is used wherever an electrical contact point is to be protected from moisture. The individual wires made of flexible conductors are referred to in the following as "stranded". As the electrically conductive material of such strands in particular copper and aluminum and alloys of these materials are used. A field of application for the strands is, for example, the engine compartment of motor vehicles. Here, with regard to the sealing of the joints between strands and contact elements moisture and other environmental influences and vibrations must be considered. In known methods, for example, a protective body made of insulating material is injected around a connection point in an injection molding tool. In another known method, a hose made of shrinkable material, which is coated on the inside with sealing material, is pushed over a connection point which, after being heated, lies tight against its base. Both methods are not only expensive, but they can not ensure the required seal also, because neither the spray material of the protective body nor the sealing material of the hose penetrates sufficiently deep between the individual wires of the strand. Also a between the conductor and its insulation existing gap is not sealed in both methods, so that in the joint penetrated moisture can also penetrate in the longitudinal direction of the conductor. It may then cause a short circuit at the far end of the conductor and cause corrosion in the joint, which can quickly destroy it.
Die eingangs erwähnte
Der Erfindung liegt die Aufgabe zugrunde, das eingangs beschriebene Verfahren so zu gestalten, daß eine wirksame Abdichtung der Verbindungsstelle zwischen Litze und Kontaktelement gegen Feuchtigkeit erreicht wird.The invention has for its object to make the method described above so that an effective seal the connection point between the strand and contact element is achieved against moisture.
Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Patentanspruchs gelöst.This object is achieved according to the characterizing features of the claim.
Bei diesem Verfahren wird ein zunächst fließfähiges Dichtungsmaterial in ausreichender Menge auf die Verbindungsstelle zwischen Litze und Kontaktelement, insbesondere auf die Litze, aufgetragen, das aufgrund seiner Viskosität in die Litze eindringt. Das Dichtungsmaterial wird in einer solchen Menge aufgetragen, daß es sich bis über die Isolierung der Litze erstreckt, so daß auch der Spalt zwischen Litze und Isolierung durch das Dichtungsmaterial verschlossen wird. Dabei dringt das Dichtungsmaterial, zumindest auf einer kurzen Strecke, in den Spalt zwischen der Litze und der dieselbe umgebenden Isolierung ein. Andererseits erstreckt sich das Dichtungsmaterial auch bis über das Kontaktelement, so daß die Verbindungsstelle von oben her vollständig feuchtigkeitsdicht abgedeckt wird. Das wird durch die unterhalb der Verbindungsstelle angeordnete, an der Isolierung der Litze und am Kontaktelement anliegende Folie ermöglicht bzw. vervollständigt, die als Begrenzung für das Dichtungsmaterial dient. Zwischen dem Kontaktelement und der Folie wird eine räumlich begrenzte Abstandshalterung angebracht. Das Dichtungsmaterial legt sich dann auch von unten an das Kontaktelement an. Die Folie verbindet sich fest mit dem Dichtungsmaterial, so daß sich ein rund um die Verbindungsstelle geschlossener und nach dem Aushärten des Dichtungsmaterials stabiler Dichtkörper ergibt. Er dichtet die Verbindungsstelle insgesamt wirksam gegen Feuchtigkeit ab.In this method, an initially flowable sealing material is applied in sufficient quantity to the connection point between the strand and the contact element, in particular the strand, which penetrates into the strand due to its viscosity. The sealing material is applied in such an amount that it extends beyond the insulation of the strand, so that the gap between the strand and insulation is closed by the sealing material. In this case, the sealing material penetrates, at least over a short distance, into the gap between the strand and the insulation surrounding it. On the other hand, the sealing material also extends beyond the contact element, so that the connection point is completely covered moisture-tight from above. This is made possible or completed by the foil arranged below the connection point and resting against the insulation of the strand and the contact element, which serves as a boundary for the sealing material. Between the contact element and the film is a spatially limited Spacer mounted. The sealing material then also attaches to the contact element from below. The film is firmly bonded to the sealing material, so that there is a closed around the junction and after curing of the sealing material stable sealing body. Overall, it effectively seals the joint against moisture.
Das Verfahren nach der Erfindung wird anhand der Zeichnungen als Ausführungsbeispiel erläutert.The method according to the invention will be explained with reference to the drawings as an exemplary embodiment.

Im vorliegenden Fall wird die Litze 1 mit einem Kontaktelement 4 aus Metall elektrisch leitend verbunden, das zu einem beliebigen, nur schematisch angedeuteten elektrischen Gerät 5 gehört. Das Kontaktelement 4 kann beispielsweise ein flacher Streifen mit rechteckigem Querschnitt sein. Es kann aber auch eine andere geometrische Form haben. Die Litze 5 wird an ihrem freien Ende mit Vorteil so zusammengefaßt und mit Vorteil verdichtet, daß keine Einzeldrähte 3 seitwärts abstehen. Anschließend wird die Litze 1 mit dem Kontaktelement 4 elektrisch leitend verbunden, beispielsweise verlötet, mit Vorteil aber verschweißt. Das Verdichten und Verlöten bzw. Verschweißen der Litze 1 mit dem Kontaktelement 4 können auch in nur einem Arbeitsgang ausgeführt werden. Eine durch diese Behandlung entstandene, gestrichelt umrandete Verbindungsstelle V geht schematisch aus
Zunächst wird eine Folie 6 aus Isoliermaterial von unten an die Verbindungsstelle V angelegt oder die Verbindungsstelle V wird auf die Folie 6 aufgelegt. Dann wird gemäß
First, a
Anschließend wird ein zunächst fließfähiges Dichtungsmaterial von oben auf die Verbindungsstelle V aufgebracht, vorzugsweise direkt auf die Litze 1. Das kann beispielsweise durch Gießen oder Auftropfen oder auch mit Einsatz einer Art Spritze erfolgen. Als Dichtungsmaterial geeignet sind beispielsweise Polyvinylchlorid, Polyurethan, Polyamid, Silikonkautschuk sowie Fluorethylenpropylen und Perfluoralkoxypolymer. Es kann aus nur einem Material bestehen, aber auch als aus zwei unterschiedlichen Komponenten bestehendes Material ausgeführt sein. Das fließfähige Dichtungsmaterial dringt zwischen die Einzeldrähte 3 der Litze 1 ein. Es wird bei seiner Bewegung nach unten durch die Folie 6 abgefangen, so daß es sich nur in der Verbindungsstelle V selbst und um dieselben herum ausbreiten kann.Subsequently, a first flowable sealing material is applied from above to the joint V, preferably directly to the strand 1. This can be done for example by pouring or dripping or using a kind of syringe. Suitable as a sealing material are, for example, polyvinyl chloride, polyurethane, polyamide, silicone rubber and fluorinated ethylene propylene and Perfluoralkoxypolymer. It can consist of only one material, but also be designed as consisting of two different components existing material. The flowable sealing material penetrates between the
Dabei dringt das Dichtungsmaterial zumindest auf einer kurzen Strecke auch in den zwischen Litze 1 und Isolierung 2 der Leitung L bestehenden umlaufenden Spalt ein, der dadurch verschlossen wird. Das Dichtungsmaterial kann sich wegen der Abstandshalterung 8 auch zwischen Kontaktelement 4 und Folie 6 ausbreiten. Es erstreckt sich abschließend auf der einen Seite bis über die Isolierung 2 der Leitung L und auf der anderen Seite bis über das Kontaktelement 4. Das Dichtungsmaterial härtet nach seinem Aufbringen relativ schnell aus, so daß sich ein mechanisch stabiler Dichtkörper 7 ergibt, der die Verbindungsstelle V wirksam gegen Feuchtigkeit abdichtet.In this case, the sealing material penetrates at least over a short distance in the between Litz 1 and
Die aus beliebigem Material bestehende Abstandhalterung 8 kann beispielsweise als Scheibe ausgeführt sein oder aus Rippen bestehen, die jeweils vor Anbringung der Folie 6 an der Isolierung 2 des Leiters 1 und an dem Kontaktelement 4 auf derselben angeordnet bzw. befestigt werden können.The existing of any material spacer 8 may for example be designed as a disc or consist of ribs, which can be arranged or mounted on the same before mounting the
Zur Durchführung des Verfahrens werden keine aufwendigen Werkzeuge oder Formgeber benötigt, weil das Dichtungsmaterial ohne begrenzende Bauteile - bis auf die Folie 6 - auf die Verbindungsstelle V aufgebracht werden kann.To carry out the method no expensive tools or shaper are needed because the sealing material without limiting components - can be applied to the joint V - except for the
